摘要： PURPOSE:To improve durability by inserting an elastic member between an inner tube member and an outer tube member, inserting a sliding member between the elastic member and the inner tube member, inserting a rigid sleeve member between the elastic member and the sliding member, and fitting a seal member with metal to its end section. CONSTITUTION:In this bush assembly suitable to be used at the pivotable connection section of the suspension of a vehicle, a cylindrical rubber block 14 is inserted between a cylindrical inner tube member 10 and an outer tube member 12 made of metal and located concentrically. A metal sleeve 16 with relatively high rigidity and a pair of oil-bearing polyacetal resin cylinders 18, 18 which are sliding members are inserted between the rubber block 14 and the inner tube member 12. A cylindrical extension section 42 is formed at the end section of the sleeve 16, and a stop ring 20 is press-fitted inside this extension section 42 and outside the end section of the inner member 10. A ring-shaped seal member 24 with metal is inserted between this stop ring 20 and the sleeve 16 for sealing.

摘要： PURPOSE:To make an intrinsic torsion spring actin reducing effect by a slide member so as to be brought into full play, by sealing a space between a cylindrical extension part of a rigid sleeve and an outer circumferential surface of a retainer. CONSTITUTION:A rigid sleeve 16 is interposed between an elastic member 14 and a slide member 18, while an end part of the rigid sleeve 16 is constituted of an outer flange part 38 and a tubular cylinder part 42. In addition, seal rubber 24 is installed in this tubular cylinder part 42, and this seal rubber 24 is made contact with an outer circumference of a retainer 20. With this constitution, since penetration of earth, sand or the like is checked by the seal rubber 24, an intrinsic torsion spring actin reducing effect by the slide member 18 can be brought into full play.

摘要： PROBLEM TO BE SOLVED: To provide a method for realizing vibration proof characteristics effective against vibration in a wide frequency or amplitude range by forming a sea-island structure with a specific rubber material as the matrix dispersed with specific particles, in order to shift the dynamic magnification-loss tangent value to the low dynamic magnification-high damping side. SOLUTION: This method comprises dispersing (A) a rubber material as the matrix, showing a certain dynamic magnification and loss tangent (tan δ) with (B) finely crushed vulcanized rubber particles showing higher damping than the component A to form a sea-island structure, in order to impart new vibration proof characteristics to the component A by shifting the dynamic magnification-loss tangent value to the low dynamic magnification-high damping side. Dynamic magnification is defined as dynamic spring constant divided by static spring constant (dynamic spring constant/ static spring constant), wherein the former represents vibration transfer and the latter support rigidity. Loss tangent (tan δ) is defined as loss modulus divided by storage modulus (loss modulus/storage modulus), wherein the former represents dynamic modulus whose phase is 90 deg. deviating from the strain's and the latter is dynamic modulus whose phase is the same as the strain's.

摘要： PURPOSE:To restrict the slip between both members of the outside and the inside by inserting an inside member as a composing element into the inside of an outside member composing a propeller shaft, and locating elastic members in a cavity between both the members, and compressing the elastic members to the radial direction. CONSTITUTION:An outside member 1 of a propeller shaft is formed in a metal cylinder and is connected to a driving system, and an inside member 2 formed in a metal cylindrical shape is connected to a drive system. Multiple rubber- made elastic ring members 3 vulcanization-processed are located with predetermined spaces on the peripheral surface of the inside member 2 and are vulcanization-adhered to the peripheral surface thereof. Next, the outside member 1 in which the inside member 2 is inserted is processed by drawing to compress cavities between both the members of the inside and the outside, and the elastic members 3 are compressed and deformed. A channel 4 surrounding in the circumference direction is formed in the center of the peripheral surface 5 of the elastic member 3, and the adhesive coated in the channel makes the elastic member 3 adhere to the outside member 1 as time goes by, and the slip is restricted by the resiliency of the elastic member 3 and the adhesive.

摘要： PURPOSE:To prepare a cylindrical rubber elastic body for sliding type eye bush at a low cost under securing the superior slidability, by preparing the rubber elastic body from the rubber composition in which silicone and silicone oil in each specific weight ratio for a rubber material. CONSTITUTION:The silicone oil compounded with a rubber material for the rubber elastic body 18 of an eye bush 14 is a straight chain polysiloxane having a relatively low polymerization degree, and possesses a dynamic viscosity of 10-300 centistokes, and the superior sliding function is provided. Further, the silicone oil is compounded in a rate of 2-20wt.pts. for 100wt.pts. of the rubber material. When the compounding rate of the silicone oil is tool low, the self lubricity or sliding function is not sufficiently developed, while if the rate is too large, the workability or moldability in kneading work of the rubber compound are deteriorated, and the physical properties of the obtained rubber elastic body are deteriorated.
